My husband and I both said that we were not interested in a relationship when we started talking. Less than two years later we are married with a one month old baby. LOL

We had no expectations beyond being friends but it didn't take it long to blossom into so much more so I say just take things as they come and enjoy your relationship on whatever level you are on without expectations. If it is meant to become more then it will if not then just enjoy what you do have.
